An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators … See more The value of optically coupling a solid state light emitter to a semiconductor detector for the purpose of electrical isolation was recognized in 1963 by Akmenkalns, et al. (US patent 3,417,249). Photoresistor-based … See more An opto-isolator contains a source (emitter) of light, almost always a near infrared light-emitting diode (LED), that converts electrical input signal into light, a closed optical channel (also called dielectrical channel ), and a photosensor, which detects … See more Usually, optocouplers have a closed pair configuration.

WebThe Makerfabs ESP32-S3 Parallel TFT Touch is an excellent choice for the ESP Display family. This 3.5 inch Touch is equipped with ESP32-S3, a dual-core Wi-Fi and Bluetooth 5 microcontroller SoC that operates at up to 240 MHz. It has 4MB Flash and 320KB SRAM, making it ideal for makers interested in ESP32-S3 RISC-V architecture. WebIsolated digital inputs provide galvanic isolation between a sensor input, or other input type, and a logic output for a host controller interface. Compared to traditional optocoupler solutions, our isolated digital input devices provide a simple, low-power alternative with an accurate current limit. This alternative to optocouplers enables the ...

WebYou may just be able to connect it (resistor plus LED) to the switch and control board ground. Or add a resistor to the third pin of the switch and put the opto-isolator between third pin and another. Which will short out the LED in the opto-isolator when the pump isn't running and the switch is in the other position.
